Need to see how exactly you have your panels wired up, but it is not good to have different panels into 1 MPPT input.
The SPF6000 is lying to you, I have seen this odd behaviour. If you have a heavy load on one side of the split output, it seems to think that is the total load on both sides. I am still looking into this but as long as you know your load is OK, igmore the SPF reading for now.
